Mortal blood!

"What Fellow Daoist Lin said makes sense. We have been in the Boundless Sea for more than ten days. Besides, I have given you all enough benefits. Please don't give up halfway!"

The Candle Dragon Patriarch really followed Lin Fan's instructions.

This made Lin Fan's vigilance increase.

Seeing this, the others naturally couldn't object.

They all dived into the sea water to look for the traces of the Red Flame Dragon.

At this moment, Lin Fan silently observed the terrain around him.

Suddenly, a strange smile appeared at the corner of his mouth.

"Yan'er, this place looks familiar. If I'm not mistaken, it should be not far from the cave of Emperor Lin."

While sneaking in the sea water, Lin Fan secretly sent a message to Mu Yan.

After taking a closer look, Mu Yan nodded in surprise.

"Master is right. This place is not far from the cave of Lin Xiandi. Why don't we look for it nearby and determine the location of Lin Xiandi's cave first?"

"Okay!"

Lin Fan agreed. On the surface, he seemed to be looking for the location of the Red Flame Dragon, but in fact, he was looking for the location of Lin Xiandi's cave.

About an hour later, Lin Fan and Mu Yan really found a hidden cave.

It was at the bottom of a sea more than a hundred feet deep.

Although there were extremely powerful protective formations around the cave, Lin Fan did not use much means.

He only dripped a drop of blood on the protective formation, and the protective formation was automatically opened at a high speed.

"This... Lin Xiandi, this pit, seems to have a conscience. I'm afraid he knew that his descendants would come here. Therefore, he can set up the procedure of blood opening the formation."

Lin Fan secretly complained.

He quickly released his divine thoughts to explore the surroundings.

It was found that the hidden formation outside Lin Xiandi's cave was very powerful.

Otherwise, after so many years, it would have been discovered by other cultivators.

"If something unexpected happens later, this place can be our temporary foothold." Lin Fan said.

But at this time, he did not dare to stay in the cave of Emperor Lin Xian for too long.

After quickly making a mark, he closed the formation and left quickly.

Not long after, a sound transmission note appeared in front of Lin Fan.

"Fellow Daoist Lin, come quickly, we have found the dragon cave of the Red Flame Dragon."

The person who spoke was the Candle Dragon Ancestor.

Hearing his anxious and excited voice, Lin Fan sneered.

"The old man, the Candle Dragon Ancestor, has ulterior motives. It seems that when we enter the dragon cave, his means should also be used, right? If I don't go, I'm afraid I will be blatantly calculated by him in the future."

Lin Fan thought secretly for a while, and suddenly felt embarrassed.

At this moment, another sound transmission note appeared in front of Lin Fan again.

After Lin Fan quickly activated it, he found that it was sent by the Candle Dragon Ancestor again.

"Fellow Daoist Lin, please hurry up. We found Sanyang Black Iron in the Jiaolong Cave. We are waiting for you to come and share it."

At this moment, the struggle in Lin Fan's heart was completely replaced by a touch of joy.

"Sanyang Black Iron? This is an extremely pure gold-attributed refining material. The attack power of the life magic weapon refined with Sanyang Black Iron is very strong and sharp."

"Even without spiritual power, it can cut iron like mud."

"Now, I have gathered the refining materials of the other four attributes. Next, I just need to get Sanyang Black Iron, and then I can try to refine the life magic weapon."

Lin Fan was secretly ecstatic.

Thinking of this, he no longer hesitated, and turned into a stream of light and disappeared rapidly into the depths of the sea.

After a meal, Lin Fan came to a water-blocking formation deep under the sea.

Ancestor Zhulong and others had been waiting in front of a huge cave for him to come.

"Fellow Daoist Lin, we just went in and found Sanyang Black Iron in the Jiaolong Cave. There is a lot of it."

"Even if we divide it equally among several of us, each of us can get hundreds of kilograms."

"However, the location of Sanyang Black Iron is right where the Red Flame Jiaolong hides. Therefore, we must first deal with the Red Flame Jiaolong before we can get the Sanyang Black Iron."

The Candle Dragon Patriarch looked indifferent.

When Lin Fan heard this, he sneered secretly.

"Is there really such a coincidence in the world? If there is, it is probably man-made, right?" Lin Fan said secretly.

But at this time, Lin Fan did not point it out.

He glanced at the others and found that these people looked at him and nodded seriously.

Lin Fan did not think much about it.

"Since all Daoists agree, I have no objection." Lin Fan said.

"Okay, let's go into the Jiaolong Cave now."

The Candle Dragon Patriarch agreed and took the lead to lead everyone in.

In the Jiaolong Cave, the cave is very vast.

Even if Lin Fan and others rushed in, it seemed very spacious.

Moreover, the further they went inside, the more moonstones were inlaid on the walls around them, making the cave as bright as day.

Along the way, others were amazed, but Lin Fan remained calm.

When they were about to reach the deepest part of the dragon's secret cave, Lin Fan quietly called out Mu Yan and asked her to hide in the dark to support him in case of any accidents.

After everyone continued to walk forward for a full meal, they finally saw the red flame dragon again.

At this moment, the red flame dragon was curled up in a cave of more than a hundred feet in size.

Pieces of Sanyang Xuan iron, as big as fists and emitting hot flames, were being pressed under the body of the red flame dragon.

It seemed that this evil beast actually used Sanyang Xuan iron to build a nest.

This luxury really made Lin Fan and others complain.

"Fellow Daoists, don't feel sad. Once we kill this evil beast, its three-yang black iron will be ours."

The Candle Dragon Patriarch smiled faintly and immediately called on everyone to activate the Five Elements Flag.

Boom!

Another dazzling Five Elements light column suddenly burst out.

It shot directly towards the Red Flame Dragon.

When it was about to fall on the Red Flame Dragon, the Red Flame Dragon dodged with a flick of its body.

Then, everyone activated the Five Elements Flags one after another.

The strange thing is that this Red Flame Dragon can successfully escape a disaster almost every time.

Seeing this, a grumpy Jindan stage bearded man was extremely angry.

"Fellow Daoist Candle Dragon, we can't kill the Red Flame Dragon with just the Five Elements Flag. I'll try to attack with my own natal sword first!"

As he spoke, the bearded man directly activated his own natal sword and stabbed the Red Flame Dragon.

This time, the Red Flame Dragon not only did not dodge, but instead crashed into the bearded man.

Crack!

With a muffled sound, the bearded man in the early stage of Jindan was killed by the Red Flame Dragon in an instant without even a scream.

Seeing this, everyone was shocked and broke out in a cold sweat, and retreated one after another.

But the ancestor Zhulong had a cold expression and blocked everyone's way.

"Fellow Daoists, if you don't help me kill this evil beast, do you want to steal my spirit stone?"
